UNITE!) STATE JAMES JOSEPH HAYES, OF KANSAS CITY, MISSOURI.

CLAMP.

Application filed April 20, 1925.

This invention relates to clamping devices for use by carpenters and others and its object is the provision of a novel device by means of which a door, window sash, or other similar building element may be held in upright position while it fitted with looks, or otherwise treated.

An important object is the provision of a device of this character which is fully adjustable whereby to permit of its holding sashes, doors or the like of widely different thicknesses.

Another object is the provision of a device of this character which embodies a spring and which is so constructed and arranged as to automatically grip against the opposite sides of the article being held whereby the clamping action will be automatic.

An additional object is the provision of a device of this character which will be simple and inexpensive to manufacture, easy to use and adjust, positive in action, efficient and durable in service, and a general improvement in the art.

lVith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which 2- Figure 1 is perspective view of the device in use,

Figure 2 is a side elevation of the device, the article held thereby being shown in section,

Figure 3 is a detail section on the line 33 of Figure 2, and

Figure 1 is a plan view of one of the clamping members alone.

Figure 5 is a detail perspective view of the spring member and the holding screw therefor.

Referring more particularly to the 'drawings, I have shown my device as comprising a pair of members and 11 which are somewhat similar in construction and which may be formed as castings or possibly stampings. These members 10 and 11 are formed respectively with elongated hollow base portions 12 and 13 and at the under sides of their outer ends they are also provided with depending lugs 14ladapted to bear upon a floor or other surface Where the device is employed. The members 10 and 11 include upstanding portions 15 between which may be engaged a door indicated at A, or a winis being planed,

Serial No. 24,653.

doW sash or other to be worked upon.

Secured within the hollow base portion 12 of the member 10 is an elongated leaf spring 16 which projects through a' slot 17 in the upright portion 15 and which extends to a considerable distance beyond the face and within a slot 18 in. the member 11. The means for holding the spring 16 within the hollow base member 12 is here represented as being a screw 19 which is threaded into a projection 20 which depends from. the top portion of the hollow base portion 12. The opposite sides of the hollow base portion 13 of the member 11 are formed with elongated slots 21 along which is movable a transverse tacit 22'about which is coiled the free end of the spring 16 as shown at 23. The bolt 22 is equipped with a suitable nut 24 whereby a clamping action may be had for holding the spring 16 in any desired adjusted position depending upon the space needed between the upright portions of the clamping members. 111 order that the device might be anchored upon the floor or other surface, I provide one side of the clamping members 10 and 11 with bosses 25 through which are slidably engaged penetrating members 26 such as nails or the like adapted to be driven into the floor or other surface.

In the use of the device, it is adjusted so that the members 10 and 11 are substantially the same distance apart as the thickness of the door, sash or other object to be held. The device is of course placed upon the floor and the article to be held is inserted between the members 10 and 11 so that it will rest upon the spring 16'. lVhen the weight of the article comes upon the spring it is quite evident that the two members 10 and 11 will fulcrum upon the feet 14 and their confronting faces 15 will move toward each other and exert a very firm gripping action upon the article so that slipping thereof will be prcvented.

This clamping device is a simple and eiii' cient means by which doors or windows can be supported upon edge so that a carpenter can easily plane the upper edge, or mortise or otherwise treat the material that he is working upon or with. The heavier the article, the steadier the clamp will hold it in view of the peculiar action of the two end portions of the device. The clamp may be placed upon the floor and by one turn of the thumb screw is loosened so as to fit any similar building element door, window, board or other similar article. Furthermore, it will be quite apparent that slipping of the article which is being worked upon will be absolutely prevented. The device is equally well adapted tor use when cutting miters or jointing extra long, large boards, frieze, base-boarcs and the like, the device being capable of being placed on staging, horses or bench, depending upon the nature of the article worked upon. The device is easily adjustable and as it is preferably constructed of malleable iron or the like it will not easily break and should consequently have a long life.

From the foregoing description and a study of the drawings it will be found that I have thus provided a simply constructed, inexpensive and easily adjusted clamping device which will be a great saver of time and labor especially when used by carpenters engaged in planing and fitting doors and windows or applying looks or other accessories thereto. Owing to the simplicity of the construction it is apparent that there is little to get out of order so that the device should have a long life and satisfactorily perform all its functions.

VJhile I have shown and described the preferred embodiment of the invention, it should be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will notdepart from the spirit of the invention or the scope of the sub-joined claim.

Having thus described my invention, I claim A device of the character described comprising a pair of substantially similar angular members each having a hollow base portion and an upright bearing face, a spring extending across from one member to the other within the hollow base portions thereof, a securing element within one hollow base portion anchoring one end or the spring thereto, the other end ot the spring being formed with an eye, an adjusting: screw passing through said eye and carryiug a nut, the opposite sides of the hollow base portion of the other member being formed with elongated slots for the accommodation of the screw whereby said members may be adjusted toward or from each other to vary the space between the bearing faces thereof, both of said members being formed with lateral projections and penetrating elements extending through said projections and adapted to be driven into the floor or other support for effecting mounting of the device in a stationary manner.

In testimony whereof I atiix my signature.

AMES JOSEPH HAYES.
